FAQ

Take Control of Welding Power Sources

The PurgeNet™ Machine Interface Lead is designed for communicating the current oxygen readings from your PurgEye® Weld Purge Monitor® to another piece of equipment, such as a Welding Power Source. This integration allows for automated control, ensuring consistent weld quality, especially for critical welds.

Key Features and Benefits

Seamless Communication and Control

Automated Welding Control: All HFT® PurgEye® Weld Purge Monitors® reading down to 10 ppm (excluding the PurgEye® Nano) can control the start/stop function on a Welding Power Source using the PurgeNet™ Machine Interface Lead.
Consistent Quality: Essential for critical welds, ensuring that the welding power source automatically pauses the process if oxygen levels fall below the set threshold, preventing weld oxidation.

Comprehensive Integration

Direct Connection: The lead connects directly to the port on the Weld Purge Monitor® and includes connections for optional accessories like the PurgeAlarm™ Visual Alarm Indicator™.
Industry Standard Communication: Oxygen readings are communicated through the industry standard 4020A current loop and relay signals.
Versatile Power Supply: The interface includes a power supply to charge/power your PurgEye® from a standard 12-24V supply found in most industrial machines.

Technical Specifications

Output and Status Indicators:

Linear Current Output: For PurgEye® Weld Purge Monitors® with a 10 to 1000 ppm range, the current output from the interface is linear, with 4mA representing 0 ppm and 20mA representing 1,000 ppm, with a resolution better than 1 ppm.
Dual Range for PurgEye® 600 Touch:
0 – 1,000 ppm: 4mA - 12mA
1,000 – 250,000 ppm: 12mA - 20mA
Status Light Indicators:
Slow Flash: Correctly powered and receiving valid data from PurgEye®.
On: Correctly powered but no data received from PurgEye®.
Off: Not powered, ensure correct current loop and supply connections.

Your Questions Answered

What is the PurgeNet™ Machine Interface?

PurgeNet™ Machine Interface communicates the current oxygen readings from your PurgEye® Weld Purge Monitor® to another piece of equipment, such as a Welding Power Source.

Which Weld Purge Monitors® are compatible with the PurgeNet™ Machine Interface?

The PurgeNet™ Machine Interface is compatible with the PurgEye® 200, PurgEye® 500 Desk, PurgEye® 600, PurgEye® 1000 Remote, and PurgEye® 1500 Site.

How does the PurgeNet™ Machine Interface connect?

The PurgeNet™ Machine Interface is a lead connecting to the Weld Purge Monitor® port. It also facilitates charging and the use of other PurgeNet™ accessories.

How are oxygen readings communicated?

Oxygen readings are communicated through industry-standard 4020A current loop and relay signals. If the oxygen content falls below the set PPM level, the welding power source automatically switches off, pausing the welding process until the PPM level rises again.
The PurgeNet™ Machine Interface Lead ensures you maintain full control over your welding processes, enhancing quality and reliability for critical applications.

CLIENT TESTIMONIALS

"The purge meters are second to none."

"I am a huge fan of Huntingdon products and have talked to others over the years about using them. The purge meters are second to none. I own and use regularly my PurgEye 100 and my PurgEye 300. I think somewhere, I still have my original Argweld® MKV monitor, which sadly no longer powers up. I am a scarce breed because I have 3 degrees and a complete academic understanding of metallurgy, but more importantly, welding science; I also have over 20 years of hands-on experience in welding on drill floors, firing lines, and vessel shops. I quite literally have a passion for old-fashioned welding! Excellent product, guys!"

"One of the best, if not the best, residual oxygen detector instruments on the market."

"I believe the PurgEye to be one of the best if not the best, residual oxygen detector instruments on the market with its digital residual oxygen level LED display readouts measuring as low as 0.01% and its large, user-friendly viewing screen making it easier for me to read. I also believe the PurgEye has great accuracy in residual oxygen, with speedy measurements displayed within seconds. The PurgEye is a far cry from the old school homemade 'use a cigarette lighter' to check purge gas flow system."

"Purge monitors are a necessity."

"I can personally vouch for purge monitors. When working with medium to large-diameter exotic pipework, they can prevent you from having a terrible day! I've only used the older model, which was a godsend. Anyone, from the welder who has had to carry out weld repairs due to root weld oxidation (or coking) on such materials, to the directors facing an expensive bill for re-work and possible tarnished company reputation, to the client with their project now running behind schedule - knows exactly what I mean. Purge monitors are a necessity."
